Deleting a project breaks the UI

[adam-coster]

Removing a project puts the app into a state where it is unable to set any remaining project as the current one.

No errors are shown, and rebooting the app doesn't help.

Temporary workaround:

1. Open Stitch Desktop
2. Go to Settings (bottom left)
3. Click the configuration file link at the top
4. Manually edit the JSON file to change the current project from null to an existing id from one of the projects
5. Restart Stitch Desktop

This just happened on my end too.

Closing due to deprecation of Stitch Desktop in favor of Stitch for VSCode.

See #138 for details.
